java - How to wrap text the numbers?

Question

The numbers are from a text file being scanned in my Java code and I was wondering if it's possible to "wrap text" the peak numbers so it's easier to view them when I run them? The examples is down below with the code under.

This is what it looks like:

Answer 1

You could alter your display section so it prints a new line when a certain number of peaks been already printed on the same line; Something like:

 int peaksOnSameLine = 0;
 int maxPeaksPerLine = 20; // for example, just 20 per line

 System.out.print("PEAKS: ");
 for (int i = 0; i < peakNum; i++) 
 {  
     peaksOnSameLine++;
     System.out.print(grid[peakX[i]][peakY[i]] + " ");
     if (peaksOnSameLine == maxPeaksPerLine)
     {
        System.out.println();
        peaksOnSameLine = 0;
     }
  }
